Medical Xpress / New therapy eliminates gum disease bacterium while preserving beneficial oral microbes
Researchers at Nagoya University in Japan have created an innovative treatment for periodontitis that targets and eliminates harmful bacteria while preserving beneficial oral microbes essential for health. The findings were ...
Phys.org / Backpack lab finds wastewater contamination and drug-resistant bacteria in Galápagos waters
From routine surgeries to cancer treatment, modern medicine depends on drugs that can fight infections caused by microbes such as bacteria, viruses, fungi and parasites. But some microbes are becoming resistant to the drugs ...
Phys.org / Long-term study suggests landfill methane emissions are far higher than estimates
Methane is an especially potent greenhouse gas, causing much more warming than carbon dioxide on a unit-for-unit basis—and a new, uniquely long-term study of emissions at a New Jersey landfill suggests that estimates of methane ...
Phys.org / Turning one of the world's most difficult plastics into premium lubricant
Virginia Tech chemist and chemical engineer Guoliang "Greg" Liu and his lab have developed a process that converts the plastic polyvinyl chloride (PVC) into polyalphaolefin, a key component in lubricants such as engine oil. ...
Phys.org / Ant teams beat gravity-based puzzle solvers
Ants live in highly organized colonies and cooperate daily to tackle a wide range of problems. Their striking group behaviors have fascinated biologists for centuries and even inspired the development of various artificial ...
Phys.org / Attosecond X-ray method maps early electron motions that trigger chemical reactions
All chemistry starts with a push from electrons. In the early moments of a chemical reaction, it's the movement of electrons that initiates the breaking of old chemical bonds and forging of new ones, transforming one molecule ...
Medical Xpress / A new drug that can potentially overcome cancer therapy resistance
Researchers at Baylor College of Medicine have developed a drug called CS18 that disrupts cancer cells' ability to survive therapy. The findings, published in Science Advances, support exploring the possibility of using CS18 ...
Phys.org / A new species of Ice Age toad discovered at La Brea Tar Pits: The spadefoot toad Spea labreae
For the first time, researchers have discovered a new species of extinct amphibian from Ice Age Los Angeles at La Brea Tar Pits: a spadefoot toad they have named Spea labreae. Only one other extinct Pleistocene amphibian ...
Phys.org / 'Spooky' particles transit DC suburbs, a step toward a quantum network
In early 2025, special signals wended their way through a fiber-optic highway strung above the streets and sidewalks of the Maryland suburbs. The arrival of those signals at their destination marks a significant step toward ...
Medical Xpress / Why do people's pupils dilate when they're surprised? Researchers explain
When people encounter new information that challenges their expectations, their pupils are likely to dilate. This physiological response is a sign that something is happening in the brain to help the person adapt to the new ...
Phys.org / Simulations hint at a hidden population of companionless black holes
So far, almost all stellar-mass black holes detected by astronomers have been found in binary systems. However, astronomers have long suspected that these binary black holes are the exception and that, within the Milky Way, ...
Medical Xpress / Microplastics cross placenta-like barrier and disrupt key pregnancy hormones in new cell model study
Tiny, near-invisible fragments of plastic shed from the products we use every day through sunlight and mechanical wear have been quietly working their way deep into the human body. Microplastics have already been found in ...
